Before entering the cyclotron, the particles are accelerated by a potential difference V. Find the speed v with which the partic
vesna_86 [32]

Answer:

Speed, v=\sqrt{\dfrac{2qV}{m}}

Explanation:

The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.  

Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.

The work done by the particles is equal to the kinetic energy stored in it such that,

qV=\dfrac{1}{2}mv^2

v is the speed with which the particles enter the cyclotron

So,

v=\sqrt{\dfrac{2qV}{m}}

So, the speed with which the particles enter the cyclotron is v=\sqrt{\dfrac{2qV}{m}}. Hence, this is the required solution.

An aluminum block has a density of 2.70 g/mL. If the mass of the block is 24.60 g, find the volume of the substance.
harina [27]

Volume of a substance can be determined by dividing mass of the substance by its density.

That can be mathematical shown as:

Density=Mass/Volume

So, Volume=Mass/Density

Here mass of the substance given as 24.60 g

Whereas density of the substance is 2.70 g/mL

So,

Volume=Mass/Density

=24.6/2.7

=9.1 mL

So volume of the substance is 9.1 mL.

How do waves interact with matter ?
velikii [3]
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.
